Mound-shaped matrix covered by green Duftite and small Calcite crystals with groupings and single larger Calcites to 3.5cm. Minor chipping to some edges but in overall great condition and very showy from all angles, good from all sides. A very sculptural and attractive Calcite.

Undamaged cluster of yellow Smithsonite crystals on matrix. Crystals reach 2cm in size. A good example of Tsumeb Smithsonite, considered teh world's best, and no longer being found.

Gemmy bright Dioptase crystals over a Duftite coated matrix. Nearly a floater, well crystallized all around with just a couple small areas of damage/contact on the backside. Very bright and colorful.

Undamaged 'snowflake' of Cerussite with small crystals of green, cuprian Smithsonite attached to the front. Complete and good from both sides, both front and back sides shown.

Divergent sprays of Azurite crystals on a bit of white matrix. These are the uncommon GEM Azurites from Tsumeb that show great color and transparency when backlit.  Good pointed termination on most crystals.  A few crystals have ragged, unterminated ends but these are natural and not damaged. A rare old treasure.

Highly aesthetic Tsumeb Dioptase, decidedly more colorful than most with the presence of the baby blue Plancheite spheres. The Dioptase occurs as both small drusy crystals coating Calcite rhombs and larger, highly lustrous crystals to 1.8cm.
